Thank you for your feedback. I have read the information that you have provided. You mentioned that you are experiencing an issue where the administrator account cannot be found and the user profile service fails. I understand how bad you feel right now.
Don't worry, you can also try the following methods to troubleshoot the potential problem.
1. You can enable the built-in administrator account via Advanced Options:
1. On the lock screen, tap the Power button, then hold down the `Shift` key and tap Reboot. The system will enter the Advanced Boot Options menu. 2.
2. In the Advanced Boot Options menu, select Troubleshooting.
3. In the Troubleshooting menu, select Advanced Options.
4. In the Advanced Options menu, select Command Prompt.
5. Enable the built-in administrator account
At the command prompt, type the following command and press `Enter`:
net user administrator /active:yes
6. Close the command prompt and restart the computer.
2. Logging in with the built-in administrator account
After rebooting, you should be able to see the built-in administrator account on the lock screen screen. Select the administrator account and log in.
3. Repair user profiles
After logging in to the built-in administrator account, you can try to repair the corrupted user profile:
1. Open Registry Editor
Press `Win + R`, type `regedit`, and then press `Enter`.
2. Navigate to the following path
`HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList`.
3: Locate the key that corresponds to the corrupted user profile. You can click any key under the ProfileList folder in the left sidebar, and then view the user name path indicated in the Data column of ProfileImagePath.
4: Double-click on the Profile's Status DWORD and change the value data to 0, then click Enter.
5: Repeat step 4 for the RefCount DWORD. If this DWORD is not available, create it by right-clicking on the space in the right pane, clicking New, then clicking DWORD (32-bit) Value, and naming it RefCount. RefCount to create this DWORD.
6: Restart the computer.

4. If the problem persists after trying the above, you can try creating a new user account:
